DRESS-GUARD FOR BICYCLES.

SPECIFICATION formingpart of Letters Patent No. 671,816, dated April 9,1901.

Application filed July 24. 1900.

1'0 00% whom it ma concern:

Be it known that I, LESTER D. COOLEY, a citizen of the United States,residingat Bat tlecreek, county of Calhoun, State of Michigan, haveinvented a certain new and useful Improvement in Dress-Guards forBicycles; and I declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification;

This invention relates to clothes-guards for bicycles, and has for itsobject-an improved guard adapted to be attached to the frame of abicycle and arranged to extend over a portion of the chain and a portionof the front sprocket-wheel and to prevent the trousersleg of the userof the bicycle from catching between the chain and the sprocket-wheel.

In the drawings, Figure l is a side elevation showing the guard inposition with respect to the sprocket-wheel. Fig. 2 is a plan showingthe guard and the brackets by which it is attached to the frame. Fig. 3is a sectional elevation showing the means by which the guard proper isadj ustably connected to its supporting-brackets. Fig. l is a rearelevation of the guard proper.

The guard consists of a cover A, arranged to engage over the chain B andover the top rear quadrant or the top half of the front sprocket-wheel.The guard A has side walls 'a and b, the inner or lower edges of whichare curved to a line that is .concentric with the wheel when the guardis in position on the wheel. The two dropping side walls a and b areunited by a cross-wall c, that forms the top of the guard, and theforward part of this is curved concentric with the inner or lowerboundary. Toward the rear the crosswall 0 diverges from the lowerboundary on a line which is substantially tangent or parallel to atangent thereto, and the side walls a and b are continued to the rear ofthe tangent cross-wall. At the rear the vertical walls a and b areunited by a cross-wall which extends upward, but stops below the top,leaving an opening for the chain. At the extreme rear the top of thecasing bends upward slightly, giving a wide vertical mouth to thepassage for the chain. The upward bend of the top of the casing isespecially useful when Serial No. 24,636. (No model.)

the attachment is used with that class of hicycles in which the drivingsprocket-wheel is journaled on a lower plane than the sprocketwheel andin which the upper run of the sprocket-chain is on a nearly horizontalline, so that without the broadened opening the chain would approachclosely to the case.

That side of the guard which lies next to the posts or frame of thebicycle is provided with two curved slots (1 and e.

O and D indicate two brackets arranged to engage the frame and to beheld thereto by curved binding-plates E and F and bybolts f g h It.

The bicycle-chain or sprocket-chain enters the case at the rear underthe top cross-wall 0, between the side walls a and b, above the rearcross-wall K, and passes forward entirely closed in by the guard.

The guard can be adjusted by means of the bolts, which pass through theslots 01 and e from the brackets, and any suitable relation between thetop wall 0 and the chain can be secured by means of such adjustment.

The guard is preferably made in two parts X and Y, the division betweenthe parts on a vertical line 00 'y longitudinal of the guard.

What I claim is- 1. A dress-guard for bicycles comprising a coveradapted to extend over the top and upper rear quadrant of thesprocket-Wheel, provided with side walls, and with a rear wall unitingthe side walls beneath the chainopening, one of said side walls beingprovided with arched slots d, 6, whereby the guard can be adjustablysecured to the bicycle, substantially asdescribed.

2. A dress-guard comprising a cover adapted to extend over the top andupper rear quadrant of the sprocket-wheel and provided with an openingfor the entrance of the sprocketchain thereinto, widened by curving thetop of the cover upward to form a verticallywide month, one of the sidewalls of the guard being provided with arched slots, whereby it isrotatively adjustable, with respect to the sprocket-wheel, substantiallyas described.

In testimony whereof I sign this specification in the presence of twowitnesses.

LESTER D. COOLEY.
